Subject of the issue

I tried sh ./kicker start in DinD(docker-in-docker) mode and got the error ./kicker: line 103: syntax error: bad function name.

Your environment

Ubuntu 22.04 LTS
Docker version 20.10.17

Steps to reproduce

create a container from docker:dind image

docker pull docker:dind
docker run --privileged -d --name dind-test docker:dind

build an image using the Dockerfile below and create a container with it.
```
FROM docker:rc-git
LABEL feliciss = <fiveswind@gmail.com>
```

Install bash, ncurses, git, curl, yarn, npm, make, cargo, docker, docker-compose and openssl-dev dependency

RUN apk add --no-cache bash ncurses curl yarn npm make docker-compose openssl-dev gcc musl-dev

RUN curl https://sh.rustup.rs -sSf | sh -s -- -y

Add .cargo/bin to PATH

ENV PATH="$HOME/.cargo/bin:${PATH}"

Install cargo packages

RUN cargo install moleculec ckb-capsule

docker build -t test-image . docker run -it test-image -v /var/run/docker.sock:/var/run/docker.sock


3. clone the godwoken-kicker repo and try to start kicker

git clone https://github.com/RetricSu/godwoken-kicker.git cd godwoken-kicker sh ./kicker start


### Expected behavior
start with no error

### Actual behavior
got error `./kicker: line 103: syntax error: bad function name`

Thanks for reporting, @sleepyyj. The above error indicates that some functions are not POSIX-compliant. It would work if you switched to bash or zsh shell, such as bash ./kicker start or ./kicker start, for temporarily using.

Are you interested in helping fix this problem? In order to meet POSIX requirements.
